Hello. I am new to these forums so I hope I am posting this in the correct place.

My employer just ordered two new HP machines running Windows 7. I took them out of the box to get them up and running and ran into a problem on one of them. I'm new here so I don't know much at all about their network, but I do know they statically assign IPs with the exception of a small block that they reserve for DHCP for users coming in for meetings, etc.

When I set the properties to connect with DHCP, it works without issues. However, since this is PC is going to stay on our network indefinitely, they want it to have a static IP. When I try to set a static IP address for the Local Area Connection (under the IPv4 properties), I can't connect to the Internet. I see this when I go to Network Connection Details:

I can see that it's getting the static IP address, but for some reason it's also getting another IP address automatically assigned. I did the exact same setup on the second machine with a different IP address and it works without any problems. However, the Network Connection Details for that computer shows a Connection Specific DNS Suffix of SGT.AUTOMATION.NET, which I didn't enter anywhere. I only put in the IP, Subnet, Gateway, and DNS servers.

Is there a setting that needs to be disabled to stop the autoconfiguration so that I only get the static IP address I entered? Any help would be much appreciated. Thank you!

Okay, I finally had a chance to work on this some more, and disabling the DHCP Client Service did not resolve the problem. I disabled the service, stopped the service, and logged out and back in as the user. Still couldn't get to the Internet. When I look at the details of the connection, they are the exact same as the details in my first post. I just don't get it - it says DHCP isn't enabled, but it's still giving an address automatically. Out of the box, the other computer (exact same) worked just fine, and I did the exact same thing to both machines. We even tried another IP address, because that's the only thing in setup that is different, and got the same result. I just don't get it.

Click on Start => in Quick search type the word cmd on the blank field. From the black screen, type the word ipconfig /all and press enter. Right click on the black screen or Command prompt then choose Select All and Paste the results here.

Let's try something else since than computer won't be there permanently, rather than modifying the registry of that computer. There's a Tool called NetProfiles that you may assign Static IP. As soon assigned the Manual IP in that Tab, all you need to do is Activate that Tab.

Thank you for all your help 2xg, I was able to get it to work. I didn't have to download the tool you suggested, I'm honestly thinking it was a problem with the IP address. The tech guy gave me two different IP addresses to use (the first right away and the second when we had problems). I tried a third one on my own today and it worked, so I'm thinking he just keeps crappy records and both IPs were assigned to other things. Would that have caused the Autoconfiguration to kick in since it couldn't connect with the IP I specified? I'm not really sure, all I know now is that it works. Thank you for all of your help. I apologize if I wasted too much of your time!
